Consider the following frequency distribution. Class Frequency 2 up to 4 26 4 up to 6 54 6 up to 8 86 8 up to 10 26 a. Calculate the population mean.
Answers
Answer:
The population mean is of 6.1667.
Step-by-step explanation:
Total sample size:
26 + 54 + 86 + 26 = 192
Mean:
To the mean is the sum of the midpoint of the class frequencies multiplied by its frequency(mean of 2 to 4 is 3, 4 to 6 is 5 and so on...). So
[tex]M = 3\frac{26}{192} + 5\frac{54}{192} + 7\frac{86}{192} + 9\frac{26}{192} = \frac{3*26 + 5*54 + 7*86 + 9*26}{192} = 6.1667[/tex]
The population mean is of 6.1667.

b. 349.661.

Answer:
a. 341.902.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
n instances of a normal variable:
For n instances of a normal variable, the mean is [tex]n\mu[/tex] and the standard deviation is [tex]s = \sigma\sqrt{n}[/tex]
60 days, for each day, mean 6, variance of 12.
So
[tex]\mu = 60*6 = 360[/tex]
[tex]s = \sqrt{12}\sqrt{60} = 26.8328[/tex]
What is the 25th percentile of her total wait time over the course of 60 days?
X when Z has a p-value of 0.25, so X when Z = -0.675.
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]-0.675 = \frac{X - 360}{26.8328}[/tex]
[tex]X - 360 = -0.675*26.8328[/tex]
[tex]X = 341.902[/tex]
Thus, the correct answer is given by option A.

Step-by-step explanation:
angle b+45 degree=110 degree (because they are vertically opposite angle and vertically opposite angle are always equal)
angle b=110-45
angle b=65 degree
angle a + angle b + 45 degree = 180 degree (being linear pair)
angle a + 65 + 45 =180
angle a + 110=180
angle a=180-110
angle a=70 degree
angle c + 20 degree=angle a (because they are vertically opposite angle and vertically opposite angle are always equal)
angle c + 20 = 70
angle c = 70 - 20
angle c =50 degree

Put the quadratic into vertex form and state the coordinates of the vertex.
y = x2 – 10x + 9
What is the vertex form?
Answers
Answer: y=(x-5)^2-16
Answer:
Step-by-step explanation:
First, we need to use the formula -b/2a.
We get 10/2 which equals 5.
Now we have our x-coordinate. Now we need to find out y-coordinate. We have to plug 5 back in as x to get the y-variable.
5^2 - 10(5) + 9
25 - 50 + 9
34 - 50
-16
Now that we have our x and y coordinates, we can make our vertex.
(5,-16)
Finally, we need to put this into vertex form. We see that the vertex form is y = a(x-h)^2 + k. We plug the x variable into the h value and the y variable into the k value. We don't need the a variable because we are only looking for the vertex and the vertex form.
y = (x-5)^2 - 16

Answers
Answer:
Length of arc AB = 4π
Step-by-step explanation:
Formula to get the arc length is given by,
Length of arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = central angle subtended by the arc AB
r = Radius of the circle

Prove the formula that:
((∃x)(F(x)∧S(x))→(∀y)(M(y)→W(y)))∧((∃y)(M(y)∧¬W(y)))
⇒(∀x)(F(x)→¬S(x))
Answers
Step-by-step explanation:
Given: [∀x(L(x) → A(x))] →
[∀x(L(x) ∧ ∃y(L(y) ∧ H(x, y)) → ∃y(A(y) ∧ H(x, y)))]
To prove, we shall follow a proof by contradiction. We shall include the negation of the conclusion for
arguments. Since with just premise, deriving the conclusion is not possible, we have chosen this proof
technique.
Consider ∀x(L(x) → A(x)) ∧ ¬[∀x(L(x) ∧ ∃y(L(y) ∧ H(x, y)) → ∃y(A(y) ∧ H(x, y)))]
We need to show that the above expression is unsatisfiable (False).
¬[∀x(L(x) ∧ ∃y(L(y) ∧ H(x, y)) → ∃y(A(y) ∧ H(x, y)))]
∃x¬((L(x) ∧ ∃y(L(y) ∧ H(x, y))) → ∃y(A(y) ∧ H(x, y)))
∃x((L(x) ∧ ∃y(L(y) ∧ H(x, y))) ∧ ¬(∃y(A(y) ∧ H(x, y))))
E.I with respect to x,
(L(a) ∧ ∃y(L(y) ∧ H(a, y))) ∧ ¬(∃y(A(y) ∧ H(a, y))), for some a
(L(a) ∧ ∃y(L(y) ∧ H(a, y))) ∧ (∀y(¬A(y) ∧ ¬H(a, y)))
E.I with respect to y,
(L(a) ∧ (L(b) ∧ H(a, b))) ∧ (∀y(¬A(y) ∧ ¬H(a, y))), for some b
U.I with respect to y,
(L(a) ∧ (L(b) ∧ H(a, b)) ∧ (¬A(b) ∧ ¬H(a, b))), for any b
Since P ∧ Q is P, drop L(a) from the above expression.
(L(b) ∧ H(a, b)) ∧ (¬A(b) ∧ ¬H(a, b))), for any b
Apply distribution
(L(b) ∧ H(a, b) ∧ ¬A(b)) ∨ (L(b) ∧ H(a, b) ∧ ¬H(a, b))
Note: P ∧ ¬P is false. P ∧ f alse is P. Therefore, the above expression is simplified to
(L(b) ∧ H(a, b) ∧ ¬A(b))
U.I of ∀x(L(x) → A(x)) gives L(b) → A(b). The contrapositive of this is ¬A(b) → ¬L(b). Replace
¬A(b) in the above expression with ¬L(b). Thus, we get,
(L(b) ∧ H(a, b) ∧ ¬L(b)), this is again false.
This shows that our assumption that the conclusion is false is wrong. Therefore, the conclusion follows
from the premise.

Let h represent the height of the light house. At point A:
tan(10) = h / 796
h = 140.36 feet
At point B, let d represent the horizontal distance from B to light house:
